Minecraft has different locations. What is the lower world. There are various, anomalous buildings that add charm to the game. The Rocks + mod was created in order to add this atmosphere to the standard world.
The addon adds new elements to the cube world. Among them will be: new blocks, buildings, anomalies, etc. Most of them consist of new blocks. The screenshots below provide examples. Meteorites look especially cool.
The author has worked on generating the world. In some moments Minecraft will look more realistic than before.
